POSITIVE-ELECTRODE PRE-LITHIATION AGENT, AND PREPARATION METHOD AND APPLICATION THEREOF: abstract simplified (18322289)

• This abstract for appeared for patent application number 18322289 Titled 'POSITIVE-ELECTRODE PRE-LITHIATION AGENT, AND PREPARATION METHOD AND APPLICATION THEREOF'

Simplified Explanation

The abstract describes a new type of material called positive-electrode pre-lithiation agent. This agent includes a catalyst and a lithium-rich material. The catalyst is made of an oxide positive-electrode active material and has a specific crystal structure. The catalyst's role is to help the lithium-rich material decompose and release active lithium. The lithium-rich material can be any of the following: lithium oxide, lithium peroxide, lithium fluoride, lithium carbonate, lithium oxalate, or lithium acetate.

Original Abstract Submitted

The present disclosure relates to positive-electrode pre-lithiation agents. One example positive-electrode pre-lithiation agent includes a catalyst and a lithium-rich material, where the catalyst is an oxide positive-electrode active material, an intensity ratio of a crystal plane diffraction peak of the catalyst to a crystal plane diffraction peak of the catalyst is less than or equal to 2, the catalyst is configured to catalyze the lithium-rich material to decompose to release active lithium, and the lithium-rich material includes at least one of lithium oxide, lithium peroxide, lithium fluoride, lithium carbonate, lithium oxalate, or lithium acetate.
